Asked whether he felt any obligation to turn on the style, Wilmots declared himself satisfied with his players - who could make it three wins from three at Brazil 2014 against South Korea in Sao Paulo today.

“It’s not about being beautiful, but about being effective,” said the 45-year-old. “Belgium are through to the next round and that is what counts. We are tactically very disciplined and we needed to be patient.”

Wilmots, who went to four World Cups as a player, could rest some of his key men against the Taegeuk Warriors.

Eden Hazard and Kevin De Bruyne are among those who may be spared, with Premier League stars Nacer Chadli, Kevin Mirallas and Adnan Januzaj all hoping for starts.

Romelu Lukaku, who was frustrated at being taken off against Russia, could also find himself on the bench on today.

South Korea must win big and hope the result of the parallel Algeria vs Russia match goes their way.

Coach Hong Myung-bo said: “We will now do our best to the end of the competition. That’s the only option we have left.”
